Our guide (Conor) was poised, informative, and quite funny. He started at the very beginning -- how Boston's geography looked before the arrival of Europeans. Very interesting!
The tour's promise of being capped at 15 people did not right true -- I'd bet there were more than 30 in our group! But Conor's microphone/speaker really helped make everything he said perfectly audible. It ended with our guide recommending we go explore the North End for lunch, which we did!
